Centos 7 lockup
...un OpenNMS stopped working last night - no hardware alarm lights, but keyboard/monitor/network unresponsive. After a reboot I see a large stack of messages like this in /var/log/messages: ---- Aug 20 14:02:34 opennms-h-03 python: SELinux is preventing /usr/sbin/monitor-get-edid-using-vbe from mmap _zero access on the memprotect . ***** Plugin mmap_zero (53.1 confidence) suggests ************************* If you do not think /usr/sbin/monitor-get-edid-using-vbe should need to mmap low memory in the kernel. Then you may be under attack by a hacker, this is a very dangerous access. Do contact yo...

[PATCH] virtio-blk: make the queue depth configurable
Couple more bikesheddy things: Is there ever a reason to use a non __builtin_const_p(perms)? Maybe that should be a BUILD_BUG_ON too BUILD_BUG_ON(!builtin_const_p_perms) My brain of little size gets confused by the BUILD_BUG_ON_ZERO(foo) + vs BUILD_BUG_ON(foo); as it just seems like more text for the same content. Is there any value on the "_ZERO(foo) +" I don't understand?

[RFC] Supporting ARM's SVE in LLVM
...ion) is worth highlighting because it can simplify the vectorization of more loops. ### IRBuilder Interface: ```cpp Value *CreatePropFF(Value* P1, Value *P2, const Twine &Name = ""); ``` ### Fixed-Width Behaviour: Same as scalable. ### SelectionDAG: See [*ISD::PROPAGATE\_FIRST\_ZERO*](#isdpropagatefirstzero). ## *shufflevector* ### Syntax: `<result> = shufflevector <ty1> <v1>, <ty1> <v2>, <ty2> <mask>` ### Overview: Not a new instruction but *shufflevector* is extended to accept non-constant masks. For code that expects the origin...
